HostApi::run_command drives the real OCS command through the same primitives
the automation channel uses, synchronously on the host thread: run a line,
start a command and answer point/text/token/entity/selection/enter prompts, or
cancel (closing anything the command opened). Refused while another command is
active, for a denylist (QUIT, NEW, OPEN, SAVE*, PY_* ...) and off the active tab.
Python: doc.command, doc.start_command and doc.modify (offset, trim, extend,
fillet, move, copy, rotate, scale, mirror, erase). Real-IPC audit checks exact
geometry for every wrapper plus guards and undo; IPC and Python unit tests; docs.

active_command_metadata listed one input kind per step. A point step that
also takes keyword letters (point_step_accepts_keywords) reports
SingleToken, so MOVE and COPY's base point with [Displacement] were
described as accepting only token and enter, and the input example was the
D keyword, though the step takes a point. List point as well; the keyword
letters are still listed as token from the options.
Equal was applied through a generic gather-then-apply flow and, with the
default size-retaining solve mode, never changed anything: the solver
held both sizes and the relation could not be met. Now:
- GCEQUAL joins ECONSTRAINT and GEOMCONSTRAINT Equal; both objects are
picked inside the command (`Select first object or [Multiple]:`,
`Select second object:`; Multiple gathers `Select objects to make equal
to the first:`), a selection made beforehand is not used, a miss says
`No object found.` and re-asks, an unsupported object or the same object
twice is reported and re-asked, a repeat is refused.
- The follower is resized in place before the relation is added: a line or
straight polyline segment keeps its start and direction and its end
moves to the first object's length; a circle or arc keeps its center and
takes the radius.
- During edits the side that is not being edited follows the same rule:
its size is not retained, its start (or center) and other vertices are
held and its direction kept, so only its length or radius changes; a
chain of Equal relations follows along.

A minimized window has a 0x0 surface; the renderer's screenshot path
panicked on the empty read-back buffer and took the whole application
down. The capture op now checks the window size first and answers with
an error instead of requesting the screenshot.

On the web build, {"op":"open","path":…} resolves the name against the
browser's recent-files cache, so a file that is not already there cannot be
opened by the control channel. Accept {"op":"open","name":…,
"data_base64":…} instead: the bytes go through the same parse, caching
and recovery path as a file chosen in the browser picker
(io::open_bytes_web, now shared with pick_and_load_web).
Native builds keep path-based open and reject data_base64 with
invalid_request.

- IMAGEEMBED: pack raster images into OLE2FRAME entities so a .dwg is
self-contained; 'Embed Image' entry in the XREF attach menu; control/MCP
op embed_image for external tools; dxf_name for OLE2FRAME queries.
- Scene: populate_images_from_document now rebuilds OLE2FRAME and PDF
underlay models too (they used to vanish after any XREF op).
- Printing: add PRINTER_ENUM_NETWORK pass when listing printers; GDI
spooler fallback (hayro raster at 300 DPI + StretchDIBits) for hosts
whose PDF handler registers no print verb; DEVMODE orientation with a
90-degree raster rotation fallback for v4 drivers; fix the fit-scale
precedence bug that printed blank pages.
- PDF export dialogs on Windows use the async file dialog so the native
overwrite confirmation no longer deadlocks the UI thread.
- Plot dialog: persist the chosen printer (saved on selection) and the
picked plot window across sessions; page setups with no device no
longer reset the output device.
- Community fonts: detect unresolvable .shx references on open and offer
a download from the repository's fonts/ folder (contribution guide in
fonts/README.md); custom font source URL setting for intranet font
servers; downloaded fonts resolve from the per-user fonts directory.
